Modular rooftop homes · Australia
Lightweight. Sustainable. Built for our cities.
Rooftop modular puts complete, factory-built homes on the roofs Australian cities already own. Learn how it works — structure, airspace rights, approvals and cost — then compare the models available from manufacturers nationwide.
An independent directory of rooftop-ready modular homes — compare footprints, structure and price across manufacturers.
Why Airspace
Add homes in prime, established locations without altering neighbourhood character or streetscape.
Low embodied carbon by reusing existing slabs, foundations and services instead of building new.
Offsite modular manufacturing delivers up to 70% faster, with minimal site noise and disruption.
Generates new strata or owner income to fund sinking funds, remediation and building upgrades.
How It Works
Structural headroom, roof geometry, access and planning pathway review.
2–4 weeks
Home configuration documented and lodged with your consent authority.
3–6 months
Your home is manufactured, fitted out and quality-assured in the factory.
10–14 weeks
Lifted into place, sealed, and connected to existing services.
1 day + fit-off
Gallery
Home modules are framed, wrapped, glazed and fitted out under cover — then craned into place as a complete home.

Why Sydney rooftops
Sydney's inner and middle-ring suburbs are full of two to six storey brick apartment buildings with flat or shallow roofs sitting unused. Those roofs are already serviced, already connected to transport, and already inside the suburbs where people most want to live.
Adding homes up there avoids new land, new roads and new infrastructure — and leaves the streetscape below essentially unchanged. It is the gentlest form of density available to an established suburb.
Rooftop homes in SydneyMany mid-century buildings were engineered with capacity to spare — an engineer confirms what your roof can carry.
Water, power and drainage risers already run to the roof, so connection works are contained.
Locations near transport and amenity where new supply is otherwise almost impossible.
Proceeds can fund remediation, waterproofing and lift works the building already needs.
Compliance & assurance
Every home is manufactured to the NCC and the Australian Standards applicable in the state of installation.
A structural engineer assesses the existing slab, columns and footings before any design is finalised.
Design, manufacture and installation are documented and certified, with statutory warranties confirmed in your contract.
Offsite production means repeatable tolerances and inspections that are difficult to achieve on a rooftop.
Fire-rated floors, walls and separation to the storey below, with egress and detection designed to NCC Section C and E requirements.
Modules are designed and tied down to AS 1170 wind and earthquake actions for the specific site exposure category.
New roof membrane, flashings and acoustic separation to AS 4654 and NCC Part F, protecting the residents below.
Lift access, hydraulics and electrical capacity are checked against the existing building before design sign-off.

Airspace basics
Yes. In Australia you can build on top of an existing apartment building if three things line up: the owners corporation resolves to deal with the common-property airspace, the local council grants development consent, and a structural engineer confirms the building can carry the added load. Lightweight prefabricated modules are the most common way to satisfy the third condition.
Legal & strata
In an Australian strata scheme, the airspace above the top floor is common property owned collectively by the owners corporation. It can be sold, leased or developed by amending the strata plan through a special resolution and registering the new lot or stratum.
Cost & finance
An 80m² modular rooftop home in Australia starts from about $349,000 for the delivered module, with a realistic all-in range of $320,000 to $450,000+ once crane access, services connections and finishes are settled. Approvals, professional fees and structural strengthening are additional and quoted per building.
